consistent handshake error in logs #199

Closed TechSec-me closed 4 years ago

TechSec-me commented 4 years ago

Hi and first off apologies if this is the wrong forum to report this, feel free to close if it is. Really like the idea behind Nebula and have setup a network to test it out but have come up with a strange issue.

I have a lighthouse with a public IP and one node on a VM on my laptop, I am seeing the error below consistently if I run a ping between the two devices. Every time the error is returned the ping time jumps considerably and as it happens every 5 or so responses it's affecting the performance. I can't see anything about the error in my searches online:

Happy to troubleshoot if there any suggestions. Thank you.

We should reduce the severity of this log line. The most likely issue you are seeing is a high latency link getting in the way between those two hosts.

As for the delay, handshake processing could likely use some performance tuning.

And just to be clear, the already seen log line stops happening after a small amount of time, correct?

TechSec-me commented 4 years ago

Hi, thanks very much for the reply, just to follow up, no the error is consistent, if I set a constant ping running it appears every 4 or so pings. I set a nmap scan running and it flooded the log.

I'll add an additional node later tonight and see if it behaves the same, might just be something on the VM. Thank you.

nbrownus commented 4 years ago

Hmm, that is interesting then. Any chance you can share the full logs from each node?

TechSec-me commented 4 years ago

Ahh it must be something to do with the particular VM. I setup an additional node and it can ping the lighthouse consistently without these errors but when I ping the original node with the new node or vice versa I'm getting these errors.

TechSec-me commented 4 years ago

So it's a virtual box VM, when I'm running the NIC in bridge mode I get these errors but if I run it using NAT everything pings fine with no errors. I'll do some more tests and if I get the exact config that's causing it I'll post here before closing the issue.

This log is with the client in Bridge mode and experiencing the issue. I've changed the WAN IPs but nothing else.

I'm curious, what version of Virtualbox are you running? This sounds like an issue in Virtualbox with not filtering the packets for each host correctly (bridge mode works by intercepting packets on your host system and redirecting them: https://www.virtualbox.org/manual/ch06.html#network_bridged )

If you google around for "virtualbox bridged duplicate packets" you can see that this is an issue that comes up often, thus why I'm wondering if you are on an older version that might be missing the fix. Regardless, this looks like an issue in Virtualbox or your network config with it and not Nebula itself.

Thanks for the reply wadey, you are correct. I was on VBox 6.0 on Ubuntu 19, I upgraded to 6.1.4 but still had the issue. Just installed Ubuntu 20.04 and VBox 6.1.4 and now I'm getting none of those errors on the same VM.

Thanks for the pointer, closing issue.
